The White House announced Wednesday that President Obama would recess-appoint Richard Cordray as chairman of the new Consumer Financial Protection Bureau, and three new members to the National Labor Relations Board.

There’s just one problem: The U.S. Senate is not in recess. The decision to appoint these officials nonetheless appears to contradict the Obama administration’s own stated position on the issue.

According to Obama’s own Justice Department, the president is in the wrong. During a 2010 Supreme Court hearing, Chief Justice John Roberts and Deputy Solicitor General Neal Katyal had this exchange, in which the latter admitted that recess appointments may not be made within three days of adjournment:

CHIEF JUSTICE ROBERTS: And the recess appointment power doesn’t work why?

MR. KATYAL: The — the recess appointment power can work in — in a recess. I think our office has opined the recess has to be longer than 3 days. And — and so, it is potentially available to avert the future crisis that — that could — that could take place with respect to the board. If there are no other questions –

CHIEF JUSTICE ROBERTS: Thank you, counsel.

Heritage’s Todd Gaziano called Obama’s move a “tyrannical abuse of power.”  Gaziano explained earlier today that the Senate is not even in a recess, which would allow a recess appointment.

The Constitution, in Article I, section 5, plainly states that neither house of Congress can recess for more than three days without the consent of the other house. The House of Representatives did not consent to a Senate recess of more than three days at the end of last year, and so the Senate—consistent with the requirements of the Constitution—is having pro forma sessions every few days. In short, Congress is still in session, and no one in Congress is saying (or can reasonably say) otherwise. It does not matter a wit that most Members of Congress are not in town voting on legislation, because ending a session of Congress requires the passage of a formal resolution, which never occurred.

Under Article II, section 2, clause 2 of the Constitution, the President has the power to fill vacancies that may happen during Senate recesses. That power has been interpreted by scores of attorneys general and their designees in the Department of Justice (DOJ) Office of Legal Counsel (OLC) for over 100 years to require an official, legal Senate recess of at least 10–25 days of duration. (There are a few outlier opinions, never sanctioned by the courts, that suggest a recess of six to seven days might be enough—but never less than that.)

The President’s purported recess appointment of Cordray would render the Senate’s advice and consent role to normal appointments almost meaningless.
